+1 for only supporting Hadoop2 initially (great work, Jesse!). It's
important that Phoenix started implementing monitoring and metrics
features. An incremental approach is the way to go IMHO.
Thanks,

Kiru, only basic equality expressions are supported for creating updateable
views. Please file a Jira if you have specific requirements for supporting
more complex WHERE clauses in updateable views.
Thanks,

Dan, TenantId can be embedded directly into a URL used to establish
connections like this. e.g. jdbc:phoenix:localhost;TenantId=jan Note the
use of a semicolon after localhost.

Hi Pari,
Phoenix supports views in version 3.0 and higher only.

You'd use with with a SELECT statement like this:
SELECT /*+ NO_CACHE */ COUNT(*) FROM TABLE1;

Guillermo, Phoenix by default puts columns into a CF named '_'. You can
specify a different CF when creating tables or columns like this:
mycf.col1, in which case Phoenix would put "col1" column into "mycf" CF,
creating it if necessary.

Right. Thanks for the correction, James.

Phoenix stores VARCHAR and INTEGER values differently so your best bet is
to create a new INTEGER column and write a script to move data from the
VARCHAR column into the INTEGER column. If you are guaranteed that all data
in your VARCHAR column are indeed numbers you can do this with a single
SELEC
Yes, should be possible, since secondary indexes are themselves Phoenix tables.

Have you looked at paging [1] using Phoenix's row-value constructors
together with the LIMIT clause? That might be what you are looking for.

To add to Vladimir's comments, I'd suggest using DATE instead of LONG for
(4). This way you'll be able to take advantage of Phoenix's support for
date functions should you need to do so in the future.

The standard JDBC way is to use Connection.getMetadata(). See if that does what
you need. You can also query SYSTEM.TABLE directly via Phoenix if you know what
you are doing.

Hi Gaurav,
Phoenix provides a way for multiple tenants to share a single table by
automatically sharding the tablespace by tenant id. This is done via
tenant-specific views. You should create a multi-tenant table over a
regular connection (no TenantId). When you open a tenant-specific
connection (

Hi Sudipta,
This is a good high-level overview of Phoenix’s multi-tenancy: https://
phoenix.apache.org/multi-tenancy.html
Are you looking for more info than what’s on that page?
CC’ing user@phoenix, since this might be useful to others.
Thanks,
